Cosmologists face a dilemma. The rise of quantitative cosmology, exemplified by the release of new data in March on the cosmic microwave background from the WMAP satellite (see pp16-19; print version ...

Astroparticle physics and particle cosmology represent converging disciplines that strive to understand the universe from its largest structures down to its most fundamental constituents. In this ...

A theory that unites quantum mechanics and general relativity claims that there was no first moment in time, but it still agrees with the predictions of classical cosmology. It's in the stars One of ...

For the past few years, a series of controversies have rocked the well-established field of cosmology. In a nutshell, the predictions of the standard model of the universe appear to be at odds with ...

No matter how elegant your theory is, experimental data will have the last word. Observations of the retrograde motion of the planets were fundamental to the Copernican revolution, in which the sun ...
